chelster commented on the word antibiotic
I prefer -tee- for the second syllable of this word (and others beginning with the prefix anti-), and the evidence of my ears says this has been the dominant pronunciation in cultivated American speech for some time. The variant with short i as in fit (listen to the American Heritage Dictionary’s pronunciation) appears in older and some current dictionaries but is far from prevalent in American speech today. In fact, the Oxford Dictionary of Pronunciation (2003) says the short i is British and -tee- is American. The variant with a long i in the second syllable (like tie) appears in dictionaries but is an overpronunciation. (“Don’t bother with long i” in anti-, the orthoepist Alfred H. Holt advised in his 1937 guide You Don’t Say. “Just rhyme anti- with panty.”) Also avoid pronouncing the antepenultimate syllable -bi- like be; say it like by. — The Orthoepist
